Ended up just getting two new Toyo backs to match the fronts, as money's getting a bit tight now. It did have 195/55/15 on the back and 185/55/15 on the front so now (obviously) it's got 185/55/15s all the way round and feels so much more planted on the road...... which seems strange to me, how come less width (that's right isn't it??) on the back feels better?
And coo-er blimey, had the bottom arms, ARB links, strut mounts and track rods replaced and it feels SOOOOOO much better. No little bumps, the steering's tight and precise and it goes in a straight line when I accelerate and brake now - happy days

Got it compression tested too, apparently all fine there, but it's losing oil from the sump gasket (easy fix innit) - just the clocks to go, and a full weekends cleaning and I reckon she's finished

What an excellent car!!
